2. Hydrological Assessment Five typhoons including HAGPIT, JANGMI, BAVI, MAYSAK and HAISHEN affected in our country in 2020. These typhoons caused Gales, heavy rain, torrential rain and storm surge, and brought great damage in several sectors in our country. Especially, under the impact of Ty MAYSAK and Ty HAISHEN, there occurred devastating flood in several areas nationwide.

3. Socio-Economic Assessment Recent years, our country has been affected by typhoon-related disasters. Last year, our country had affected by TY 13, and this year, had been affected by 3 typhoons including TY 8, TY 9 and TY 10. Due to the catastrophic typhoons, Tens of personal injury was reported, more than thousands of houses collapsed, more than hundreds of public buildings damaged, tens of hectares of crops affected, hundreds of kilometers of railroad and road destroyed, and its direct economic losses has accounted to hundreds of millions Won.

4. Regional Cooperation Assessment During the last period, we used typhoon bulletin from Tokyo, NWP products of ECMWF, CMA, JMA and NCEP for monitoring and forecasting typhoons. Also, observed data from surrounding nations were efficiently used for typhoon monitoring and early warning. It is still important that typhoon information issued from typhoon centers should be improved and developed for the typhoon monitoring and forecasting. Typhoon Committee plays an important role in reducing typhoon-related disasters in DPRK. Under the active efforts of Typhoon Committee, typhoon information issued from several forecasting centers have been used for forecasting typhoon-related disasters and reducing damages in our country.

Ⅱ. Summary of Progress in Priorities supporting Key Result Areas 1. Strengthening Typhoon Analyzing Capacity We have established typhoon analysis system using Dvorak technology, and introduced it into operational activities this year. This system enabled for us to analyze the location of typhoon center, minimum sea level pressure and maximum wind speed, and to watch and forecast typhoons in time.

2. Improvement of Typhoon Track Forecasting We have newly developed typhoon track forecasting method using technology of Ensemble partial collection. We have introduced the method into operational activities for typhoon forecasting, and confirmed its accuracy this year. It is important to improve continuously typhoon track forecasting method in the future.

3. Continued improvement of TOPS We have already developed Typhoon Operational Prediction System (TOPS) and used efficiently for typhoon monitoring and forecasting. And then, considering past forecasting experience, typhoon precipitation displaying module and typhoon searching module have been improved, and result displaying module has been added. Therefore, we could make a great advance in typhoon analyzing, forecasting and reporting.

4. Improvement of Typhoon Information Service State Hydro-Meteorological Administration (SHMA) has paid a great attention to the improvement of typhoon information according to the increased social demand on typhoon forecasting. SHMA has broadcasted information and common sense on typhoon every hour via TV and computer network, and it enabled many people to be fully prepared to cope with typhoon. SHMA will make greater efforts to improve typhoon information service in the future.

5. Effort for reducing typhoon-related disasters All activities for reducing typhoon damage have been coordinated by the government in our country. The government of DPRK had previously organized the work to minimize typhoon-related disasters at national level based on the detailed information analysis on upcoming typhoon. As the result, although our country had been continuously affected by super typhoons, its damage could be minimized. At present, the government of DPRK has immediately rehabilitated destroyed houses, public buildings and facilities with the combined efforts of the whole nation regarding damage rehabilitation as the prime task. In the future, these actions will obviously contribute to protect typhoon-related disasters in our country.
